The present invention relates to a recording and reproducing apparatus, and more particularly to a recording and reproducing apparatus that provides easy control of a program to be recorded or preset on a recording medium.

Tape recorders of the type mentioned above are described in US Pat. No. 4,224,644.

In a conventional video tape recorder, a plurality of programs are recorded on a video tape in its running direction, and a cue signal is recorded at the beginning of each program. When the user wants to play a given program from a recorded videotape, the videotape recorder is placed in survey mode to advance the tape at a high speed to the point where the program's cue signal is located and played, and the videotape recorder in playback mode. A series of operations is performed to play back the tape to determine whether a program reached is required or not.

In the above-mentioned conventional video tape recorder, data for a plurality of programs recorded on a video tape is actually located at the beginning of each individual program. This arrangement involves one drawback. That is, whenever the user wants to know whether the required program has been recorded, whenever the program is played, whenever another program is examined, or whenever a new program is duplicated in a previously recorded program, the required program is located. It is necessary to find the necessary program for a period of time until it is accessed, and to advance the videotape of the videotape recorder back and forth quickly and repeatedly.

In addition, the prior art video tape recorder detects the position of each program recorded on the video tape as program-descriptive data at the time of examination. Therefore, when it is necessary to use complex data such as timer presetting data evenly, there is a need to use a method in which the presetting data is written to a timer preset memory provided separately.

However, using this method, assigning data to each video tape fails. This is because the timer preset memory is common to all video tapes used. Thus, the presetting data cannot be used as control data of each program.

If the user wants to control a plurality of recorded or non-recorded video tapes or to control a program recorded "on a continuous basis" on a plurality of video tapes, maintaining the recording of the tape is time-consuming. It is a consumption and annoying task. This operation includes pre-recording the control data on the contents of the program recorded on the tape, the recording time of the program, and the choice of preserving and non-preserving each recorded program on the label of the video cassette and the cassette case.

As more programs are recorded and preset on the videotape, more complex problems arise, where control data is written down, data is read out and data-based decisions are made. It is therefore essential to make the necessary and record-keeping operations as simple as possible.

In particular, if multiple programs constituting a serial drama are recorded in any order on one tape, then observing the programs in the correct order later requires the user to repeatedly perform the various operations described above to access each program. do. This feature of the conventional device is inconvenient to bother the user for a long time.

The present invention relates to a recording and reproducing apparatus, and more particularly to a video tape recorder using house hold.

Conventional video tape recorders use a detection head (called a control head) to detect the position data of any program recorded on the video tape in its running direction. If a number of programs are recorded on a videotape and any of the programs are played back, the cue signal of the target program is examined and reached.

Therefore, when any of a plurality of programs recorded on a video tape is unified and overlapped with a new program, the conventional video tape recorder reaches the target program by searching for a cue signal, and a new program in the tape field containing the target program. Start recording.

Conventional video tape recorders have an erasing head on top of a magnetic head that records and reproduces video signals, and a control head below the running direction of the video tape. During operation, the lower control head arrives at a program corresponding to the target program via a program cue signal. In the located target program, the delete head deletes it continuously and the lower magnetic head writes a new program there.

The fact that the erasing head is located on top of the control head in a conventional video tape recorder involves one drawback. That is, the tape field containing the program to be deleted advances after the field containing the program to be stored, so that the upper erasing head deletes the position data (queue signal) of the continuous program field before the lower detection head detects the position data. There is a tendency. Incorrect deletion of positional data may result in the deletion of a program to be kept along the preceding program from the videotape.

Household electronic technology of the type described above allows a user to record or preset at least one broadcast program as required. When using preset data, these techniques perform many kinds of complex functions. Several methods have been devised to control input programs that make it easier to preset data. For example, a switch for setting the required item is provided to be operated manually, and a barcode reading means is used to input the required data.

Conventional preset data input means have one disadvantage in common. In other words, a device using such a household has a write-association action indicated in the machine-orientation item. Items required by the machine are indicated in letters and symbols arranged on the operation panel. The user at the operation panel selects and specifies one or multiple items as required.

These designated items are set by estimating the level at which the user understands the function and structure of the apparatus in question (ie, expressed in terms such as "record start time", "record end time", and "input" described in the instruction manual). In other words, a person who does not have this basic knowledge of the device will not be able to accurately enter the required program presetting data.

In accordance with the foregoing, it is an object of the present invention to provide a recording and reproducing apparatus which substantially simplifies the step of the user performing control of a preset and recorded program.

Another object of the present invention is a recording and reproducing apparatus for recognizing a recording area including all programs recorded on a video tape as a recording medium before the tape is operated rapidly or vice versa to access a necessary program on the tape in the shortest time. To provide.

It is a further object of the present invention to provide a data recording and reproducing apparatus which solves the inconvenience in the aforementioned conventional apparatus.

It is another object of the present invention to provide a recording and reproducing apparatus capable of superimposing a new program on a field in which a necessary program is recorded among a plurality of program recorded fields of a video tape.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In addition, by moving the cursor displayed on the display screen 6A by the four-way cursor key 6B, the predetermined display item is designated, and then, by operating the execution key 6C, a designated signal relating to the display item is input and obtained. To lose.

The remote control controller 6 also has a normal operation command key 6D, a menu table command key 6E, a management data mode command key 6F, a reserve 1 and reserve 2 operation mode designation keys 6G and 6H, and by means of this mode designation key the CPU It is possible to specify an operation mode of the video tape recorder 1 with respect to.

In step SP1 of the input information processing program RT0 of FIG. 7, the CPU 8 receives the power-on operation and judges whether or not the power-on operation is at the first time in step SP2 when a positive result is obtained, The message "SET TIME OF DAY" is displayed by sequentially executing the processes of steps SP3, SP4, and SP5 during the first time, and the display screen 4A of the monitor 4 and the remote control controller 6 After displaying on the display screen 6A, the local time is set by the system setting operation mode, and the display of "TIME OF DAY IS SET" (time setting) is displayed on the display screens 4A and 6A.

The video tape recorder 1 is in a state of receiving a command for setting a current time. This command reception state is retained even when a negative result is obtained in step SP2, and in the command reception state, "MANAGEMENT DATABASI" (management database) "SYSTEM SETTING" (system setting) "PREFERENCE SETTING (preferred) Setting) Select "TMER PRESETTING" (Timer reservation) item selectively.

In practice, the CPU 8 displays the display screens 6A and 4A when the menu display mode designator 6E is operated on the remote control controller 6 (or the keyboard 12) in this command reception state. MANAGEMENT DATABASE ”Allows the user to select one operation mode by displaying the operating mode designation of“ SYSTEM SETTING ”(Preferences) and“ TIMER PRESETTING ”. It can be specified by operating with a finger.

The management database mode records management data D _AV (see FIG. 4) in the management database video track recording area F _AVV or the management database audio track recording area F _AVA of the videotape (Fig. 3). Or an operation mode for driving control of the video tape recorder main body 3 using the recorded management data D _AV , wherein the CPU 8 manages at step SP7 when a management database item is selected from the menu display items at step SP6. It is determined whether or not the video cassette 35 having the tape on which the data D _AV is recorded (this is called the management data tape) is set, and when the set is executed, various processes of the management database are executed by the subroutine RT1. Subsequently, it is determined in step SP8 whether the contents of the management database have been changed and managed in SP9 when the contents have been changed. The processing is performed to change the recording data of the database video track recording area F _AVV or the management database audio track recording area F _AVA to be written into the management data after the change. In the management database, the processing ends, and it is determined whether or not the power is turned off in step SP10. When the negative result is obtained, the above-mentioned input information is in the command reception state and when the positive result is obtained, the input information in step SP11. End the processing program.

Upon entering the above-mentioned various processing routines RT1 of the management database, the CPU 8 displays the display screen 4A of the monitor 4 in step SP21 and is in a command reception state as shown in FIG.

On this display, “LABEL” (level) “PRESET CANCEL” (cancel reservation) “AUTO REPRODUCING” (AUTO PLAY) “MANUAL PRESET” (manual reservation), “PROGRAM INFORMATION VERIFICATION” and “MANAGEMENT DATA PRESET” (Management Data Reservation) item is displayed, thereby making it possible to specify one of them.

Here, the level item indicates an operation mode that can be set by selecting one of the volume information included in the volume information block D _VM (FIG. 4) of the management data D _AV , and a display screen showing that the "level" item is selected in step SP22. By displaying “PASSWORD” (password), “RECORDING MODE”, “TAPE TYPE” (CAT type), CATEGORY (category) and “TITLE” on the screen, you can select one of them. Will be on.

If the user selects the "Password" item here, the CPU 8 allows the user to change the password data recorded in the item A11 of the volume information D _VMX (FIG. 5) in step SP23.

In this manner, the CPU 8 can change the writing by using the title data recorded in the item B12 of the program information D _PBC (FIG. 6) in step SP24.

In this way, the CPU 8 writes and corrects the data of the password item or the title item in steps SP23 to SP27, and then ends the processing of the management database when the end item is specified in step SP28. Return to the management database processing loop shown in to enter the SP8 processing.

On the other hand, when the user selects "cancel reservation" item in the command reception state in which the management data list is displayed in step SP21 in FIG. 8, the CPU 8 reserves the entire program recorded in the management data list in step SP30. Cancel.

If the user selects the "Auto Play" item, the CPU reproduces the playback order data of item A13 of the volume information D _VMX (FIG. 5) in the predetermined order, and converts them as necessary in step SP31.

When the user selects the "manual reservation item", the CPU 8 accepts the manual setting according to a predetermined number of programs sequentially and inputs it as management data.

When the process of step SP30, step 31, and step 32 is complete | finished, CPU8 will go to the management database process routine via step SP28, SP29 mentioned above. (Fig. 7) In addition, if the user selects a program information confirmation item while the CPU 8 is in the command reception state for displaying the management database in step SP21 in Fig. 8, the CPU 8 proceeds to the processing of step SP33 and goes to step SP33. In SP34, the display of the display screen is switched to step SP35 or SP36 or SP37.

Or in SP38, a display mode in which the recording contents, viewing flag items, category items, and title items of the volume information D _VMX (FIG. 5) and the program information D _PRX (FIG. 6) can be checked or written and converted. do.

In the present embodiment, a predetermined screen display, that is, a character is used as data of the record permission item, the viewed flag item, the category item, and the title item, whereby a plurality of reserved programs are recorded with a relatively small display area. Information can be checked and changed.

When the processing of steps SP38 to SP38 ends, the CPU 8 goes to the management data processing routine (FIG. 7) via steps 28 and SP29.

By executing the subroutine RT31, the CPU 8 allows the user to select the time reservation mode type in step SP41. As shown in Fig. 11, the embodiment provides two types of timer reservation mode, language reservation mode, or graphic reservation mode, one of which is selected by the user in step SP41. In the reservation mode based on the language, the specified item is displayed in the form of an item table TBL based on the language of the native language (Japanese) state. In the graphic-based mode that is generally used, certain items are displayed in the form of a table of items based on graphics in the form of graphic elements such as letters or symbols.

If the user selects the reservation mode based on his language, the CPU 8 goes to step SP42. Here, the CPU 8 causes the language-based item table TBL to appear on each display screen and sends data corresponding to the input item based on the language selected by the user to the register 44.

On the other hand, when the user selects the reservation mode based on the graphic, the CPU 8 goes to step SP43. In step SP43, the CPU 8 displays the item item table based on the graphic on each display screen, and sends data corresponding to the graphic item selected by the user into the register 44.

After completing the necessary input operation in the above step, the CPU 8 finishes its management data reservation processing and returns to the management data processing loop of FIG.

The CPU 8 displays the items "ENTRY", "CHANGE" and "INQUIRY" on the screen. When the user selects an entry item, when the conversion item of SP51, SP52 or SP53 is selected, the CPU 8 initializes the corresponding process.

Then, according to the item selected by the user, the CPU 8 displays the reservation table weekly reservation table and the daily reservation table based on the calendar at SP54, SP55 or SP56, respectively. The user can write the starting time of each reserved program in the reservation table mentioned above. When the above setting is completed, the CPU 8 goes to SP28 to check whether the current management database processing program is terminated. The CPU 8 then goes to SP7's management database processing loop via SP29.

What was described above was about what happens when a user selects a management database entry in SP6. After making a selection, management data is written or modified on the videotape. The user also selects a system setting item, a good setting item or a timer reservation item. When either of these is selected, the CPU 8 sets the operating state for the defective portion of the video tape recorder 1.

Specifically assume that the user has selected a system setting item in SP61 in FIG. 7, wherein each display screen is user selectable in SP62 to SP69. Displays “CURRENT TIME”, “DOZE-OFF TIMER”, “RECORDING MODE”, “NOISE REMOVEL”, “BS ONLINE”, “AUTO SETTING”, “TUNER PRESETTING” and “LINE PRESETTING”. When any one of these items is selected, the CPU 8 sets the operating state for the application element of the system. After this processing is finished, the CPU 8 ends the system setting processing loop and goes to SP10.

If the user selects a favorite setting item on the SP71, the CPU 8 displays on each display screen the “PICTURE DISPLAY”, “MANAGEMENT DATABASE”, “USER SETTING”, “CHARACTER” user selectable from SP72 to SP79. , “TIMER PRESETTING”, “USER LEVEL”, “MESSAGE” and “VOICE” are displayed. When any one of these items is set, the CPU 8 performs a process corresponding to the set item. After this processing is finished, the CPU 8 goes to SP10 as described.

Assume that the user selects a timer reservation item in SP81. The CPU 8 will display items such as entries and changes on each display screen. When the user selects any of these items, each display screen will display a calendar-based reservation table item, a weekly reservation table item, and a daily reservation table item. The user selects one of these. When the user selects a calendar-based reservation table item, a weekly reservation table item or a daily display reservation table item, the CPU 8 displays a calendar-based reservation table, a weekly reservation table or a daily reservation table on each display screen. Make it appear. By using the reservation table currently displayed, the user reserves the desired program.

When the timer reservation processing loop ends, the CPU goes to SP10.

In the manner described above, the CPU 8 executes the input data processing program RT0 of FIG. This performs reliable control over the entire video tape apparatus 3 based on the data input by the user.

[(5) Reservation of management data using language input items]

As mentioned, when "MANAGEMENT DATA PRESETTING" is set from the management data list displayed on the display screen in the command standby state of SP21 (Fig. 8), the CPU 8 in the control management in the management data processing device 5 Goes to the management data processing reservation subroutine RT3, and performs management data reservation processing. At that time, the language display item table shown in FIG. 11 is displayed on the display screens 4A and 6A, so that the user can input management data through a dialogue with the computer.

When the timer setting processing is executed at SP S1 in the initial instruction standby state shown in FIG. 7, the CPU 8 displays the language setting item TBL shown in FIG. 11 on the display screens 4A and 6A. Similar to the execution of the management data reservation process, the user can easily enter an item using an ordinary language.

In the present embodiment, the table of the language display item TBL is a list of terms in which the user can input a command to the video tape recorder 1 using the native language. The chart includes terms indicating the object to be operated, terms indicating the contents of the operation, terms indicating the operating time, and so on. These terms can be arranged in a diagram in a manner designed as a group of one or a plurality of words.

In the present embodiment, an item to which a time or hour may be designated may be a day or week in which the time before and after the current time is, for example, “TODAY”, “TOMORROW”, “DAY AFTER TOMORROW”, and “NEXT WEEK” unit. Items that can be specified as a repetition, for example, items that can be specified in weekly and daily units for “EVERY WEEK” and “EVERY DAY”, dates are calendars, for example, “MONTH”, “DAY ”,“ SUNDAY ”to“ SATURDAY ”, and the time of day set according to“ IN THE MORNING ”,“ IN THE AFTERNOON ”,“ O'CLOCK ”,“ MINUTE ”and“ BETWEEN ” Contains items that may be

Items for which input resources can be set include “BS”, “LINE”, “CABLE”, “ch” and “βIII”.

Items that can be set for operation include “DISPLAY”, “CHANGE”, “CANCEL”, “CONTINUES UNTIL”, “RECORD PRESETTING”, “END”, “STOP” ... and “.”.

Items to which the above described items can be linked include "FROM", "UNTIL", "THE PROGRAM OF", "OF", "AT" and "TO". Items into which numerical information can be input include “0” to “R”. Items for the human-machine conversation using the CPU 8 include "YES" and "NO".

In this embodiment, the Table of Language Designated Items (TBL) is displayed on the display screen 6A of the remote controller 6 and the display screen 4A of the monitor 4, where the process of “MANAGEMENT DATA PRESETTING” is performed. When executed in the subroutine RT3 (Figure 8) and when the process of TIMER PRESETTING is executed (Figure 7) in step SP81, the user is indicated by the item set in the CPU 8 To enter a command, you can set one of the items created on the Table of Language Designed Items (TBL).

For example, when a program recorder running during a broadcast wants to program the first channel from 8:00 to 9:00 on Monday night, the user can select “RECORD PRESETTING”, “THE” from Table of Language Designated Items (TBL). PROGRAM OF ”,“ 1 ”,“ ch ”,“ FROM ”,“ 8 ”,“ O′CLOCK ”,“ TO ”,“ 9 ”,“ O′CLOCK ”,“ IN THE AFTERNOON ”,“ OF ”, It can be set in order of “MONDAY”, “EVERY WEEK” and “.”, Or in other order.

When those operations are "MANAGEMENT DATA PRESETTING" executed in the subroutine RT3, the input data is stored in the register 44, and then the management database video track recording area F _AVV or the management database audio track. It is recorded in the management data D _AV recording area of the recording area F _AVA . That is, the recording start time information, for example, numerical data indicating “8 O'CLOCK IN THE AFTERNOON OF EVERY FRIDAY” is used as the program information D _PRX of the program information block D _PR indicated by item B9. Is recorded. Further, information indicating the recording end time, for example, numerical data indicating "9 O'CLOCK", is recorded as the program information D _PRX indicated by the item B10. Data representing the input resource is recorded as the program information D _PRX indicated by the item B7.

When the program processing of the recorder 1 described above is one of the processes performed in the process of CHANGE of TIMER PRESETTING in step SP81, the input data is written to a new recording in the presetting information memory provided to the video tape recorder unit 3. Recorded as information.

When you want to make a change in the preset program, for example, to change the number of channels of the preset program that will continue the next day from 6 to 8 channels, you can execute the process of MANAGEMENT DATA PRESETTING of the subroutine (RT3). From the Table of Language Designated Items (TBL) to "CHANGE", "THE PROGRAM OF" "TOMORROW" "FROM" "6", "ch", "TO", "q", "ch" or other Can be set in order.

Namely, management data of the management database audio track recording area F _AVA or the management database video track recording area F _AVV as the program information D _PRX identified by Item (B7), for example, “6ch”. (D _AV ) The input resource data recorded on the recording area is already replaced by "8ch" to change the set management data.

When the program processing of the recorder 1 described above is one of the processes consisting of the process of CHANGE of TIMER PRESETTING in step SP81, the data already recorded in the presetting information memory provided to the video tape recorder unit 3 is Replaced by the input data.

If you already want to delete a preset program, for example, the preset of a program that will be broadcast next Tuesday, you can select “CANCEL”, “THE PROGRAM OF” or “NEXT” TUESDAY or another step (SP81). ) Or from the Table of Language Designated Items (TBL) displayed on the screen in the subroutine RT3.

When the above operation is executed in the process of "MANAGEMENT DATA PRESETTING" of the subroutine RT3, recording start time information of all the program information, for example, numerical data indicating "TUESDAY ON EVERY WEEK" is stored in Item (B9). The program information D _PRX identified by this is deleted and is recorded in the management data D _AV recording area of the management database audio track recording area F _AVA or the management database video track recording area F _AVV .

If the above operation is executed with "TIMER PRESETTING" in step SP81, the corresponding information stored in the memory provided to the video tape recorder unit 3 is deleted.

Since the language used every day is used in the table as the entry data entry means, the user can enter information for easier and more accurate programming into the record using the Table of Language Designated Items (TBL) shown in FIG.

[(6) Recording of Program Start Address]

When a plurality of programs (P1, P2, P3, etc.) or one program is recorded on the video tape 36, the control data processing CPU 8 starts the program data D _PRX (Fig. 6). The recording start point of each program is recorded in the address item B1 with the program start address value associated with the tape top. Then, when one of the programs recorded on the videotape 36 is reproduced or overwritten, the system can verify the recording position of the program by checking the address without actually executing the tape up to the tape position at which the program is recorded. have.

By operating the remote controller 6, the user first inputs the management data D _AV of each item (FIG. 4) as I / O data S4 through the remote control transceiver 7. The control management data processing CPU 8 places the control data in the register 44. Then, if the control data recording mode is selected, that is, when the video cassette 35 is ejected, the control management data processing CPU 8 transfers the management data (from the register 44 to the video recording encoder 51). D _AV ) is transmitted as the recording control data S25. In turn, the video recording encoder 51 converts the management data into the data video signal S42 and provides the signal to the recording circuit 32 via the recording switch over circuit 31.

At this point, the write circuit 32 processes the data video signal S42 in the same way that the write video signal S1 is processed. Thereafter, the recording circuit 32 is not only the video head (recording and reading head) constituting the magnetic head 34. The processing as a signal corresponding to a field of a video signal with the video recording tracks TA and TB (FIG. 3) on the video tape 36 via the video electromagnetic conversion circuit constituting part of the electromagnetic conversion circuit 33. Recorded signal.

Thus, the management database video track record field F _AVV (FIG. 3) is formed above the tape of the video tape 36. As shown in Fig. 12 (b), the management data video signal VD _DAV is recorded in the corresponding management database video track record field F _AVV .

During the recording operation, the mark management data is transferred to the CTL recording encoder / decoder 54 as the control management data processing CPU 8 control signal recording data S44. In turn, the CTL recording encoder / decoder 54 converts the control signal recording data S44 into a data control signal S46. The data control signal S46 is transmitted to the control signal recording track TCT on the video tape 36 via the control head which is one of the magnetic heads 34 and the control signal electromagnetic circuit constituting a part of the electromagnetic conversion circuit 33. It is recorded as a recording start point mark signal MKos (Fig. 12 (c)).

Thereafter, the control management data processing CPU 8 transmits a control signal as the control signal recording data S44. This records one control signal CTo in the control signal recording track TCT.

In the program recording mode, the control management data processing CPU 8 performs the video recording tracks TA and TB of the video signal recording field F _VD (FIG. 3) according to the management database video track recording field F _AVV . In Fig. 12 (b), the program video signals VD _P1 , VD _P2 , VD _P3 , etc. of the programs _P1 , _P2 , _P3 , etc. are continuously recorded. Along with the recording, the CPU 8 records the corresponding program audio signals AD _P1 , AD _P2 , AD _P3 , etc. on the audio recording tracks CH1 and CH2 (Fig. 12 (a)). At the same time, the CPU 8 records the control signals CT _P1 , CT _P2 , CT _P3 , etc. on the control signal recording track TCT (FIG. 12 (c)).

In the program recording mode described above, the control data processing CPU 8 forms a mark signal in the form of the control signal recording data S44 in accordance with the start of recording of the program video signals VD _P1 , VD _P2 , VD _P3 , and the like. The data is provided to the CTL record encoder / decoder 54. This records the recording start point mark signal (MK _P1S , MK _P2S , MK _P3S , etc.) as shown in FIG. 12 (c).

In the present embodiment, the mark signals MK _0S , MK _P1S , MK _P2S , MK _P3S , etc., are respectively formed on the tape on the video tape 36 with tape position address values related to the reference point. The tape position address value is clearly provided by passing the value according to the tape counter circuit in the video tape recorder unit 3 through the mechanism control CPU 11 to the control management data processing CPU 8.

In the above description, when the recorded video cassette 35 is loaded into the video tape recorder unit 3, the control management data processing CPU 8 enters the management database reproduction mode even though it is in communication with the mechanism control CPU 11; Enter it. In the management database playback mode, if the CPU 8 picks up the data video signal from the management database video track record field F _AVV on the video tape 36 and records the data in the register 44, The data is transmitted through the magnetic head 34, the electromagnetic conversion circuit 33, the reproduction circuit 37, the reproduction switching over circuit 38, and the video record decoder 52.

Thus, the register 44 holds management data D _AV (FIG. 4) therein as management data currently assigned to the video tape 36. As shown in FIG. The program data block D _PR includes program data D _PRX (FIG. 6) relating to programs P1, P2, P3, etc., recorded on the video tape 36. The program data block D _PR is a program data block.

As described, the position data including the recording start point (MK _P1S , MK _P2S , MK _P3S , etc.) is placed in the start address item B1 of each program data D _PRX . The position data constitutes an address representing each program position related to a reference position on the tape on video tape 36. In this way, registers 44 form part of the centralized controlling setup through the program in the entries of their addresses.

The user verifies the contents of the starting address item B1 including the respective program data D _PRX . This proof makes it easy for the user to know the location of any program currently recorded on the videotape 36 without having to go through chores of delivery speeds and playing the tape to know where a given program actually starts. . The user can easily obtain access to each program recorded on the tape.

[(7) duplicate description of recorded programs]

It is assumed that one of the plurality of programs (P1, P2, P3, etc.) recorded in the video track recordings TA and TB of the video tape 36 is duplicated as a new program. In this case, the control management data processing CPU 8 is shown in FIG. 13 to record the second control head 34A, the erasing head 34B, the recording and reproducing head (video head 34c), and a new program. The first control head 34D is controlled.

For example, where a new program is repeatedly described in the second program P2 (Fig. 12), the control management data processing CPU 8 first writes the second program P2 to the mechanism control CPU 11; One command is provided via the bus 10 for retrieving the starting point mark signal MK _P2S .

Upon receipt of the command, the mechanism control CPU 11 provides the video tape drive unit 57 with a control signal S7 specifying that the video tape 36 is advanced and advanced as needed.

At this point, the control management data processing CPU 8 is transmitted through the electromagnetic conversion circuit 33 and the recording and reproducing circuit 33B included in the CTL recording encoder / decoder, and the control in which the first controller has been read to have 34D. Input the signal. If the input control signal is a recording start point mark signal, the signal is transmitted to the mechanism control CPU 11 via the bus 10.

The mechanism control CPU 11 has a previously input and held recording start point mark signal MK _P2S corresponding to the second program, which is input from the control management data processing CPU 8. On the basis of this signal, the CPU 11 checks to see if the recording start point mark signal input during the search operation coincides with the previously recorded recording start point mark signal MK _P2S . If the signals match, it means that the first control head 34D has arrived in the recording start field of the second program P2. At this point, the mechanism control CPU 11 stops the video tape 36 and provides the control management data processing CPU 8 with a signal indicating the end of the search operation.

Then, the control management data processing CPU 8 allows duplicate description of the new program. In particular, the erasing head 34B erases the second program P2 from the tape. At the same time, the recording video signal S1 starts to be recorded from the start of the recorded field VD _P2 of the second program P2, the signal being written to the recording circuit 32, the switching circuit 33C and the rotating drum ( And transfers through the recording and reproducing head 34C in 3A). At the same time, the control management data processing CPU 8 controls the control signal recording track TCT of the second program P2 via the CTL recording encoder 54, the recording and reproducing circuit 33B, and the first control head 34D. New control signal recording for recording data S44 as a new control signal is started.

At this point, a new audio signal is not shown but is recorded in the audio recording tracks CH1 and CH2 via the audio head.

Since the second control head 34A is located upstream of the erasing head 34C in the execution direction K1 of the video tape 46, the control management data processing CPU 8 causes them to be the erasing head 34C. The control signal and the recording start point mark signal can be detected before being erased.

Therefore, the control management data processing CPU 8 inputs the control signal read by the second control head 34A as the control signal reproduction data S50, and the input thereof is the reproduction circuit 33A in the electromagnetic conversion circuit 33. ) And through the CTL playback decoder 55. Then, the CPU 8 waits for the third recording start point mark signal MK _P3S to be input, which signal is the initial of the field containing the third program P3 according to the second program P2 on the tape. Is written on.

As the third recording start mark signal MK _P3S is input, the control management data processing CPU 8 informs the mechanism control CPU 11 of the end of the recording operation. This prevents the third program P3 from being inadvertently erased when the new program to be recorded is longer than the second program P2 which has been repeatedly described.

Since the third recording start point mark MK _P3S is read by the second control head, the recording operation can be easily stopped before the erasing operation of the third program P3 necessary for preservation. In this way, the second program P2, which could be erased, is overwritten with a new program.

After the new program is recorded as described above, the control management data processing CPU 8 replaces the management data D _AV in the register 44 in accordance with the redundant write operation. Then, the CPU 8 rewinds the video tape 36, replaces the program data D _PRX in the management data recording field at the top of the tape, and terminates the redundant writing operation.

As described, the second control head 34A is positioned upstream of the erasing head in the direction of execution K1 of the video tape 36. According to the second control head which reads the recording start point mark signal from the video tape 36 during recording, the field in which the new program is recorded is checked continuously during its termination. Therefore, only a predetermined portion of the tape is overwritten in accordance with the new program.

((8) Embodiments Different from the First Embodiment]

(8-1) In the above-described embodiment, the management data D _AV is stored in the video recording track (while the mark signal indicating the recording start point of each program is continuously recorded in the control signal recording track TCT. TA and TB). Alternatively, the management data D _AV can be recorded on the tape of the control signal recording track TCT or on the audio recording tracks CH1 and CH2.

(8-4) The embodiment described above is an application of the present invention to a video tape recorder. Alternatively, the present invention can be applied to various other recording and reproducing apparatus, such as a digital audio tape recorder (DAT) for recording and reproducing audio signals.

(2) Second Embodiment

[(1) Recording of Management Data (D _AV ) to Management Database Video Track Recording Field (F _AVV )]

In the second embodiment, the video recording encoder 51 (FIG. 1) converts the management data D _AV into a data video signal in the setup shown in FIG. 14. The management data is in the same format as the video signal. As many signals as are recorded in the video 36. At the same time, the video recording decoder 52 converts the data video signal into management data D _AV and applies it to the control management data processing CPU 8 in the setup of FIG. 14, and the data video signal is supplied to the video tape 36. Video signals reproduced from the same format are reproduced in the same format.

In particular, in the management data recording mode, the video recording encoder 51 transmits the management data D _AV as the recording management data S25 to the encoder circuit 51A, and records the data in the video memory 53. Is converted into video data S41, and the management data D _AV is based on the basic data memory 43 (FIG. 1) based on the control data S5 for the control management data processing CPU 8; Stored as part of the data.

Video data recorded in the video memory 53 is read by the display control circuit 51B to convert the digital into an analog format to form a data video signal S42 applied to the write switch over circuit 31.

The write switch over circuit 31 is controlled according to the control data for the control management data processing CPU 8 as described with reference to FIG. Thus, when the video cassette 35 is loaded in the video tape recorder unit 3, the management recording switch over circuit selected before the recording video signal S1 is recorded in the video signal recording field F _VD (FIG. 3). Numeral 31 is controlled in accordance with the control data of the control management data processing CPU 8 as described with reference to FIG. Therefore, when the video cassette 55 is mounted in the video tape recorder apparatus 3, the management database recording mode selected before the recording video signal S1 is recorded in the video signal recording field F _VD (Fig. 3), and the recording switch over circuit Numeral 31 provides a function of providing the data video signal S42 to the recording circuit 32.

As a result, the recording circuit 32 records the data video signal S42 as a one-field video signal on the video recording tracks TA and TB (FIG. 3) on the video tape 36, and the data video signal S42 is the recording video signal S1. Similarly, from the video recording encoder 51, it is reproduced through the video head including the magnetic head 34, and the reproduced signal is the electromagnetic conversion circuit 33, the reproduction circuit 37 and the reproduction switch over circuit 38. Proceeds through the video electromagnetic conversion circuit 33A.

At this point, the video record decoder 52 includes an analog / digital conversion circuit 52A for converting the data video signal into the video data S43, so that the data video signal is output as the reproduced video signal S2. After conversion, the data S43 is recorded in the video memory 53 through the memory write control circuit 52B.

Therefore, the video data recorded in the video memory 53 is converted into the reproduction management data S44 by the decoder circuit 52C and output to the bus 9.

In FIG. 14, the control management data processing CPU 8 enters into the management database reproduction mode while communicating with the mechanism control CPU 11 when the video cassette 35 is mounted to the video tape recorder device 3. . When the switch over control signal S45 is used, the control management data processing CPU 8 switches the regeneration switch over circuit 38 to the side of the regeneration circuit 37. This means that the data video signal is transmitted from the management database video track record field F _AVV of the video tape 36 through the video electromagnetic conversion circuit 33A, the playback circuit 37, the playback switchover circuit 38, and the magnetic head 34. To the record decoder 52. At that time, the video recording decoder 52 converts the data video signal into the reproduction management data S44 and records it in the basic data memory 43.

In this situation, the management data D _AV can be superimposed or changed by specifying the "management database" item in step SP6 of FIG. 7 to activate the management database in various processing subroutines RT1 (Figure 8). In this case, the control management data processing CPU 8 contacts the mechanism control CPU 11 and proceeds to step SP9 for modification of the management database and enters into the management database recording mode. When using the switch over control signal S46, the CPU 8 switches the recording switch over circuit 31 on the side of the video recording encoder 51. This allows management data D _AV to be read from the basic data memory 43 or to be written to the video tape 36 as write control data S25 (data video signal). The data goes to the video record encoder 51, the write switch over circuit 31, the write circuit 32, the video electronic conversion circuit 33A, and the magnetic head 34.

Thus, as shown in FIG. 14, the video cassette 35 is simply loaded with the video cassette 35 in the video recorder device 3, and the user can record, change or verify magnetic data for the recorded program. Can be. Magnetic data is located in the magnetic database video track recording area F _AVV of the video tape 36. This configuration eliminates the hassle of executing the video tape in the retrieval mode or the playback mode whenever it is necessary for the user of this kind of conventional apparatus to check a predetermined program component recorded anywhere on the video tape.

Various conventional magnetic data D _AV is maintained on each video tape in accordance with the magnetic data, thereby improving the function of the video tape. When connected to an external device, the video tape recorder acts as a command center.

At the same time, the audio recording decoder 54 converts the data audio signal into management data D _AV and provides it to the control management data processing CPU 8 in the apparatus shown in FIG. 16, the data audio signal being a video tape. The audio signal reproduced from 36 is reproduced in the same format.

In particular, according to the control data S5 of the control data processing CPU 8, the audio recording encoder 53 reads the management data D _AV (FIG. 1) stored as part of the basic data in the basic data memory 43, This data is transferred to the encoder circuit 53A as the recording management data S27, and transferred to the encoder circuit 53A as the data audio signal S41, and converted into the data audio signal S41. The data audio signal S41 is provided in the electromagnetic conversion circuit 33 to the audio electromagnetic conversion circuit 33A as the recording audio signal S42, and the signal proceeds through the recording switching circuit 53B and the recording circuit 53C. . The signal is then recorded on the audio recording tracks CH1 and CH2 on the video tape 36 by an audio head comprising a magnetic head 34 (Figure 3).

As a result, the management database audio track recording field F _AVA (Figure 3) is formatted on the tape upper side of the video tape 36.

When the control management data processing CPU 8 enters the management data reproduction mode, the audio recording decoder 54 is the audio signal S43 reproduced in the electromagnetic conversion circuit 33 via the audio electromagnetic conversion circuit 33A. There is a reproduction circuit 54A for receiving the data audio signal, which is picked up by an audio head including a magnetic head 34 from the audio recording tracks CH1 and CH2 of the video tape 36.

At this time, the control management data processing CPU 8 writes the read management data S28 to the basic data memory 43 for the bus 9, and the data S28 is output from the decoder circuit 54C.

When the reproduction of the management data D _AV is terminated, the control management data processing CPU 8 uses the reproduction switching signal S47 to switch the reproduction switching circuit 54B to the side of the audio circuit 55. At the same time, the CPU 8 outputs an audio reproduction end signal to the mechanism control CPU 11. This completes the associated management database replay operation.

As shown in FIG. It is connected to 34A. In operation, the CTL recording encoder / decoder 54 converts the management data D _AV into a data control signal, and records this signal in the control signal recording track TCT in the same format as the control signal. The data control signal reproduced from the control signal recording track TCT in the same format as the control signal is converted into the management data D _AV input under the control of the control management data processing CPU 8.

That is, the CTL recording encoder / decoder 54 causes the control management data processing CPU 8 to transmit the management data D _AV as the recording management data S28W via the recording switching circuit 54A in accordance with the control data S5. The management data D _AV is held in the register 44 (FIG. 1), and the recording management data S28W constitutes the recording / reading management data S28.

Switch to the position corresponding to the data recording mode or the management data playback mode. When the recording mode or the reproduction mode is selected, the recording switching circuit 54A or the reproduction switching circuit 54F is switched to the side of the CTL processing circuit 61. Thus, in the recording mode, the recording control signal S46 is video through the recording switching circuit 54A, the encoder circuit 54B, the recording circuit 54C, the CTL electromagnetic conversion circuit 33A, and the control signal head 34A. It is recorded on the tape 36.

It is delivered from the register 44 when the CPU 8 enters the management data recording mode. As also shown in the nineteenth (c), the data control signal S41 is recorded in a control signal recording track TCT on a specific portion of the video tape 36, for example, on top of the tape.

When the recording management data S28W is logically set to 1 or 0, the encoder circuit 54B changes the duty factor of the CTL pulses constituting the control signal. This allows the write control data S28W to be changed to the data control signal S41.

In the management data recording mode, the recording switching circuit 31 is switched to the side of the video recording encoder 51. In the management data reproduction mode, the reproduction switching circuit 38 is switched to the side of the reproduction circuit 37. The switching allows the reproduced video signal S2 to reach the video recording 52.

When the control management data processing CPU 8 enters the video signal recording mode, the recording switching circuit 31 is switched to the side of the video signal processing unit 2.

At this time, the mark management signal MK recorded in the control signal recording track TCT is output to the bus 9 via the reproduction switching circuit 54F as the read management data S28R. This makes it much easier to extract managed data video signals (VD _DAV ).

Furthermore, when the video signals VD _P1 , VD _P2 , VD _P3 and the like of the programs P1, P2, P3 and the like are recorded on the video recording tracks TA and TB by the video signal processor 2, the control management data processing CPU 8 ) Records the management data at a specific position on the control signal recording track TCT, the position coinciding with the time point of each mark control signal, and the management data is registered by the mark control signals MK _P1 , MK _P2 , MK _P3 and the like. ) And proceeds through the recording switching circuit 54A of the CTL recording encoder / decoder 54 as recording management data S28W.

In this field, a management database audio signal AD _DAV is recorded.

At this time, the mark signal MK ₀ is recorded by changing the duty coefficient of the control signal CT ₀ according to the logic level of the control data, and the control signal is constituted by the CTL pulses recorded on the control signal recording track TCT.

Are simultaneously recorded on the audio tracks CH1 and CH2 via the audio signal processing circuit 71 (Fig. 21 (b)), the control management data processing CPU ( 8) switches the write switching circuit 54A of the CTL write encoder / decoder 54 to the bus 9 side. The mark signals MK ₁ , MK ₂ , MK _3, etc., are recorded at the positions corresponding to the recording start positions of the video signals VD _P1 , VD _P2 , VD _P3, such as the programs P1, P2, P3, etc., due to the switching.

The recording video tape 36 is created by the above method. When the user tries to review a predetermined program on the recording video tape 36, the user first loads the video cassette 35 into the video tape recorder unit 3. The control management data processing unit CPU 8 reads out the management data audio signal AD _DAV from the audio recording tracks CH1 and CH2 on the video tape 36 via the audio recording encoder / decoder 53 and registers this signal. Using the management data in the register 44 for the recording programs P1, P2, P3, etc., the control management data processing unit 8 reproduces, records or pre-sets the desired program as specified by the user. Set.

By attaching the mark signals MK ₀ , MK ₁ , MK ₂ and the like to the control signal recording track TCT, the video tape recorder according to the present invention quickly and accurately identifies the recording position of each program on the video tape 36. This allows the user to record, play back or preset a program on a videotape more easily than before by means of a videotape recorder as embodied above.

[(2-3) Control signal format is recorded and other signal format]

22 shows that control data is distributed and recorded not only in the control signal recording track TCL but also in the audio recording tracks CH1 and CH2. 21 and 22, the same reference characters indicate the same or corresponding parts. The format of FIG. 22 includes the addition of the format of FIG. That is, in the format of FIG. 21, when video signals VD _P1 , VD _P2 , VD _P3, etc., such as programs P1, P2, P3, and the like are recorded on the video tracks TA and TB, corresponding audio signals AD _P1 , AD _P2 , AD _P3, etc. Are recorded on the audio recording tracks CH1 and CH2. In addition to the above format, the programmable control data audio signals AD _DAV1 , AD _DAV2 , AD _DAV3 and the like are recorded at the starting points of the audio signals AD _P1 , AD _P2 , AD _P3 and the like recorded in the format of FIG. 22.

Using the format shown in FIG. 22 and setting the control management data processing CPU 8 to the management recording mode, items of management data D _AV common in the program are read from the register 44 and recorded in the audio recording encoder / decoder 53. It is supplied to management data S27W. Recording management data S27W is recorded as the management data audio signal AD _DAV in the tape head portions of the audio recording tracks CH1 and CH2 on the video tape 36.

Advantageously, when the management data audio signal AD _DAV starts to be recorded, the recording switching circuit 54A of the CTL recording encoder / decoder 54 is switched to the bus 9 side. By this switching, the recording management data S28W constituting the mark signal MK ₀ is transferred from the register 44 and recorded in the control signal track TCL.

Then, when the video signals VD _P1 , VD _P2 , VD _P3 and the like of the programs P1, P2, P3 and the like are recorded in the video recording tracks TA and TB, the control management data processing CPU 8 performs the audio recording encoder / decoder 53. The write switching circuit 53B therein is switched to the encoder circuit 53A side. This switchover transfers the management data on each program from the register 44 as the recording management data S27W. Thus, the programmatic management data audio signals AD _DAV1 , AD _DAV2 , AD _DAV3 and the like are _alternately recorded on the audio recording tracks CH1 and CH2 of the video tape 36.

When the recording video cassette 35 is loaded into the video tape recorder unit 3, the control management data processing CPU 8 indexes the video tape 36 with the management data audio signal AD _DAV1 using the mark signal MK ₀ , Then, the reproduction switching circuit 53E of the audio recording encoder / decoder 53 is switched to the decoder circuit 53F side. In this way, the management data audio signal AD _DAV1 is read as the read management data S27R in the register 44.

Then, when the video signals VD _P1 , VD _P2 , VD _P3 , etc. of the programs P1, P2, P3 and the like are reproduced from the video recording tracks TA and TB, the control management data processing CPU 8 causes the mark signal MK ₁ corresponding to the program. , MK ₂ , MK ₃ , are used to index the video tape, and the reproduction switching circuit 53E is switched to the decoder circuit 53F side. Thereby, the program management data audio signals AD _DAV1 , AD _DAV2 , AD _DAV3 and the like are reproduced from the audio recording tracks CH1 and CH2 and recorded in the register 44 as read management data S27R. Individual programs are controlled in accordance with programmatic management data.

In the alternative embodiment described above, the program management data audio signals AD _DAV1 , AD _DAV2 , AD _DAV3 , and the like of the individual programs are recorded in the audio recording tracks CH1 and CH2. Since management data specific to each program is recorded at the location where the program is recorded, the management of the individual program is much more reliable and accurate than before.

[(3) Other Embodiments of the Fourth Embodiment]

(3-1) In the embodiment of FIGS. 18 to 22, the video recording encoder 51 and the video recording decoder 52 convert the recording management data S25 into a data video signal, and the audio recording encoder / decoder 53 Converts the recording management data S27 into a data audio signal, and the CTL recording encoder / decoder 54 converts the recording management data S28W into a data control signal. All records management data is transferred from the register 44. A data video signal, a data audio signal, and a data control signal are recorded on the video tape 36. At the time of reproduction, the data video signal, the data audio signal and the data control signal are converted into read management data S26, S27R and S28R respectively by hardware for recording in the register 44. Optionally, the conversion is performed in a software base by the control management data processing CPU 8. (3-2) In the embodiment of Figs. 18 to 22, the management data D _AV includes the volume data block D _VM and the program data block D _PR in the order from the start of the recording track. Optionally, blocks are switched between blocks, subdivided into another block for different arrangements, or allocated on tape.

[5] Fifth Embodiment

[(1) Recording of Program Start Address and Program End Address]

In the fifth embodiment shown in FIG. 23, when recording one or a plurality of programs P1, P2, P3, etc. on the video tape 36, the control data processing CPU 8 also causes the start address of the address data D _PRX . Address-related data is recorded in item B1 and end address item B2 (Fig. 6), and this data indicates the program start address and the program end address of each program in terms of the program start address value and the program end address value in relation to the upper portion of the tape. Then, whenever the program on the recorded video tape 36 is played, duplicated, or otherwise accessed, the system identifies the recording position of the program without actually executing the tab until the program arrives.

When the user operates the remote controller 6 as the I / O data S4 and inputs each item of the management data D _AV (FIG. 4) via the remote control transceiver 7, the control management data processing CPU 8 The data is placed in the register 44. Then, in the management data recording mode for the embodiment, the video cassette 35 is ejected so that the control management data processing CPU 8 stores the video recording encoder 51 in the register 44 in the form of the recording management data 25. The management data D _AV is transmitted. In turn, the video recording encoder 51 converts the recording management data S25 into the data video signal S42 and supplies the signal to the recording circuit 32 for the recording switching circuit 31.

At this point, the recording circuit 32 handles the data video signal S42 in the same manner as the recording video signal S1. That is, this signal is recorded as a signal corresponding to the one field bead signal on the video recording tracks TA and TB (FIG. 3). The recording of the data video signal S42 is carried out to the electromagnetic conversion circuit 33 section via the video electromagnetic conversion circuit and to the magnetic head 34 section via the video head.

As such, the management database video track record field F _AVV (Figure 3) is formed on the tape top of the video tape. As shown in FIG. 23 (b), the management data video signal VD _DAVB is recorded in the management database video track record field F _AVV .

While the recording operation is in progress, the control management data processing CPU 8 transfers the mark recording data as the control signal recording data S44 to the CTL recording encoder / decoder 54. The CTL record encoder / decoder 54 converts the control signal write data S44 into a data control signal. Alternately, the data control signal S46 passes through the control signal electromagnetic conversion circuit which is a portion of the electromagnetic conversion circuit 33 as the recording start point mark signal MK _OS (Fig. 12 (c)), and the control signal head which is the magnetic head 34 portion. Then, it is recorded on the control signal recording track CTL on the video tape 36.

Thereafter, the control management data processing CPU 8 transmits a control signal as the control signal recording data S44. As a result, the control signal CT is recorded in the control signal recording track CTL. At the same time, the recording end point mark signal MK _OE is recorded by supplying the control signal recording data S44 once again at the end of recording in the management data video signal VD _DAV Fig. 12 (b).

In the program recording mode, the control management data processing CPU 8 executes the programs P1, P2, P3 and the like in the video signal recording field F _VD following the management database video track recording field F _AVV (Fig. 12 (b)). The program video signals VD _P1 , VD _P2 , VD _P3 , and the like, are successively recorded on the video recording tracks TA and TB. At the same time, the control management data processing CPU 8 records the corresponding program audio signals AD _P1 , AD _P2 , AD _P3 and the like on the audio recording tracks CH1 and CH2 (Fig. 23 (a)), and the control signals CT _P1 , CT _P2. , CT _P3 and the like are recorded in the control signal recording track TCL (Fig. 23 (c)).

In the program recording mode, the control management data processing CPU 8 sets the CTL recording encoder / decoder by setting the mark signal data as the control signal recording data S44 at the recording start point and the recording end point of the video signals VD _P1 , VD _P2 , VD _P3 and the like. Supply 54. This _vanishes recording of the recording start point mark signals MK _P1S , MK _P2S , MK _P3S, and the recording end point mark signals MK _P1S , MK _P2E , MK _P3E and the like (Fig. 23 (c)).

In this embodiment, each of the mark signal MK _OS and MK _OE, MK _OE and MK _P1S, MK _P1E and MK _P2S, MK _P2E and MK _P3S such as a tape position address which is proportional to the reference point on the upper tape on the video tape 36 It is composed by. The tape position address value is obtained by passing the values of the video tape recorder unit 3 tape counters to the control management data processing CPU 8, and the value is returned via the mechanism control CPU 11.

When the recording video cassette 35 is loaded into the video tape recorder unit 3 in the above-described setup, the control management data processing CPU 8 enters the management database reproduction mode through communication with the mechanism control CPU 11. First, in the management data processing CPU 8, the control management data processing CPU 8 picks up the data video signal from the management database video track record field F _AVV on the video tape 36, and registers the signal in the register 44. The signal is returned through the magnetic head 34, the reproduction circuit 37, the reproduction switching circuit 38, and the video recording decoder 52.

In this way, the register 44 retains the management data D _AV (FIG. 4) on the current video tape 36 as specific management data. The program data block D _PR retains the program data D _PRX (FIG. 6) relating to the programs P1, P2, and P3 recorded on the video tape 36. As shown in FIG.

In the foregoing manner, the register 44 is program containing the location data showing the program P1, P2, recording, such as P3 start point and recording end point MK _P1S and MK _P1E, MK _P2S and MK _P2E, MK _P3S and MK _P3E, etc. The start address item B1 and the end address item B2 of the data D _PRX constitute an arrangement of centralized management of program positions on the video tape, and each point starts or ends a predetermined program on the video tape 36 in proportion to the reference point on the tape. Address indicating a location.

Using the above arrangement, the contents of the start address item B1 and the end address item B1 of the program data D _PRX are verified in each program. This allows the user to easily know that the desired program is placed on the video tape 36 without the hassle of actually proceeding and playing the video tape quickly. Accessing arbitrary programs to videotape is easier than ever.

For example, suppose a user wants to play a program recorded on video tape 36 in a certain order. In this case, all that is necessary is to rearrange the start and end addresses of the programs included in the desired order in the control management data processing CPU 8. This simple process easily satisfies the reproduction of the recorded program in a certain order.

It is preferable to record the new program on the video tape 36 or to duplicate the new program in the pre-recorded program. In this case, the new recording position is predetermined in dependence on the register 44 which holds the start and end addresses of the recording program in a concentrated manner.

When the user wants to reach the start of any program so that the program can be adjusted as desired, the control management data processing CPU 8 starts the program from the register 44 according to the specific data input through the remote controller 6 and Read the end address. Thereafter, in communication with the mechanism control CPU 11, the control management data processing CPU 8 advances the video tape 36 rapidly, and continuously the program P1, P2, P3, etc., from the control signal head which is the magnetic head 34 portion. the signal of the mark MK, and MK _{P1E P1S, P2S} and MK _P3S MK, MK _P3E, etc. picked up. A check is made to see if the pickup mark signal matches the address input via the CTL write encoder / decoder 54. When a matched recording start point mark signal is obtained, access to the start of the desired program on the videotape 36 is completed.

When a new program is recorded on the video tape 36, the next progression occurs. When a new program is recorded, the recording start mark signal and the recording end point mark signal of the program are recorded in the control signal recording track TCL. At the end of the recording operation mode, the address indicated by this mark signal is recorded in the start address item B1 and the end address item B2 constituting the program data D _PRX of the program, respectively, and this program data is stored in the register 44 in the management data D _AV portion. to be.

In this way, a new program is written each time, and the start address data and end address data are held in the central control register 44.

When the processing of the video tape 36 is completed and the user ejects the video cassette 35, the mechanism control CPU 11 returns to the specification data supplied to the control management data processing CPU 8 via the remote controller 6. Rewinds the video tape 36 to the tape top position. At this time, the supply data is recorded in the management database video track record field F _AVV of the video tracks TA and TB as the management data video signal VD _DAV . Video cassette 35 is ejected.

As a result, the tape top of the video tape 36 holds address data indicating the recording position of each program on the tape, and this address data is specified on the current video tape 36. Whenever the video cassette 35 is loaded into the video tape recorder unit 3, the address data is easily read out for control purposes.

[(2) Other Embodiments]

24 schematically shows a recording format for use with another embodiment of the present invention. In Figs. 23 and 24, the same reference characters indicate the same or corresponding parts. As shown in Fig. 24, the recording start point mark signals MK _OS , MK _P1S , MK _P2S , MK _P3S, and the like are positioned in the control signal recording track TCT such as the control signals CT _P0 , CT _P1 , CT _P2 , CT _P3, and the like. Is recorded. At an arbitrary distance away from each recording start point mark signal, the count mark signal MK _X is recorded. Each count mark signal is composed of numerical data representing a predetermined value. In this format, the recording end point mark signals MK _OE , MK _PIE , MK _PIE , MK _P3E, and the like (Fig. 23 (c)) are not included.

When the format of FIG. 24 is used and the control management data processing CPU 8 records the management data D _AV in the management database video track recording field F _AVV (FIG. 24 (a)), the recording start point mark signal MK _{The OS} and count mark signal MK _X are recorded in synchronization with each recording start point of the video recording tracks TA and TB.

In contrast, when the program video signals VD _P1 , VD _P2 , VD _P3 and the like of the programs P1, P2, P3 and the like are recorded in the video tracks TA and TB, the control management data processing CPU 8 is different from the recording start point of the program video signal. In synchronization, the recording start point mark signals MK _P1S , MK _P2S , MK _P3S and the like are recorded, and each recording start point mark signal is followed by the count mark signal MK _X.

Assume that the format of FIG. 24 is used. Program video signals VD _P1 , VD _P2 , VD _P2 and the like of the programs P1, P2, P3 and the like are recorded in the video tracks TA and TB. At the end of the recording, the control management data processing CPU 8 writes the addresses of the recording start point mark signals MK _P1S , MK _P2S , MK _P3S, and the like into the start address item B1 of the current program data D _PRX . It is held in the register 44 as management data D _AV . At the same time, the signal of the count mark signal MK _X up to the recording end point of the current program is recorded in the end address item of the program data D _PRX .

The start and end addresses recorded in the management data D _AV are recorded in the database video track record field F _AVV as the management data video signal VD _DAV when the video cassette 35 is ejected.

When the user wants to specify and reproduce a program from the recording video tape 36, the management data video signal VD _DAV is read from the video recording tracks TA and TB and recorded in the register 44. At the same time, the control management data processing CPU 8 gains access to the start address of the program on the start of the desired program on another tape, and starts playing the program once reached on the tape.

The feed amount of the video tape 36 in the playback mode is monitored by the control management data processing CPU 8 that counts the number of count mark signals MK _X picked up from the control signal recording track TCT. When the count value matches the end address data stored in the end address item B2 of the register 44, the control management data processing CPU 8 judges the program to be reproduced to the recording end point, and stops the reproduction.

It is desirable to overwrite a new program on a tape on a pre-recorded program. In this case, the control management data processing CPU 8 receives the command signal from the remote controller 6 and reads it in accordance with the start and end addresses of the old programs that overlap in the program data D _PRX in the register 44. When the video tape 36 is advanced to the start address and stopped, the video signal processing unit 2 passes through the recording circuit 32, the electromagnetic conversion circuit 33, and the magnetic head 34 as the video input signal S1. Record the new program at 36.

The feed amount of the video tape 36 in the recording mode is monitored by the control management data processing CPU 8 that counts the number of count mark signals MK _X read out from the control signal recording track TCT. If the count value matches the end address, duplicate recording of the new program is terminated.

In the above-described manner, the new program is overwritten in the pre-specified position of the recording video tape 36 (ie, overwritten in the area between the recording start point and the recording end point).

Using the format of FIG. 24, the recording program on the video tape 36 is controlled to be as easy and reliable as the format of FIG.

(3-5) In the above embodiment, the start and end addresses are represented by data indicating some position on the video tape 36 in relation to the reference address position on the tape. Optionally, the time at which each program is recorded is used as a reference point in relation to the time at which the start and end addresses are determined.

When the preceding alternative is used and the programs P1, P2, P3 and the like are recorded, the control data processing CPU 8 (FIG. 1) causes the recording start mark signals MK _P1S , MK _P2S , MK _P3S by the date on which the program is recorded. And the like are recorded in the control signal recording track TCT.

Then, if any program on the recorded video tape 36 is played or overwritten, or otherwise manipulated, the system recognizes the recorded position of the program without actually running the tape until the program is located.

The management data D _DAV inputted by the user as needed is used to change the contents of the volume data block D _VM and to regenerate the play rank data.

When the user operates the remote controller 7 to input each item of the management data D _AV (FIG. 4) as the I / O data S4 via the remote control transceiver 7, the control management data processing unit CPU 8 Locates the input data in register 44. Then, for example, when the video cassette 35 is removed, the management data recording mode is selected. In this mode, the control management data processing unit CPU 8 holds the management data D _AV in the register 44, while transferring the data therefrom to the video recording encoder 51 as the recording management data S25. In turn, the video recording encoder 51 converts the recording management data S25 into the data video signal S42, which is supplied to the recording circuit 32 via the recording switchover circuit 31.

In this regard, the recording circuit 32 adjusts the data video signal S42 in the same manner as the recording video signal S1, and through the video electromagnetic conversion circuit which is part of the electromagnetic conversion circuit 33 and the video head which is part of the electromagnetic head 34.

Before the management data recording mode is selected, the control management data processing unit CPU 8 causes the programs P1, P2, P3, etc., to output the program video signals VD _P1 , VD _P3 , VD _P3, etc. in the video recording field F _VD. It is recorded in the video recording tracks TA and TB of FIG. 3, and the field F _VD follows the management database video track recording field F _AVV . At the same time, the control management data processing unit CPU 8 transmits the corresponding program audio signals AD _P1 , AD _P2 , AD _P3 and the like, and the control signals CT _P1 , CT _P2 , CT _P3 and the like to the audio recording tracks CH1 and CH29 (Fig. 25 (a). ) And the control signal recording track TCT (Fig. 26 (c)).

In the program recording mode, the control management data processing unit CPU 8 writes the control signal recording data S44 to the CTL recording encoder / decoder 54 in synchronization with the recording start and end points of the program video signals VD _P1 , VD _P2 , and VD _P3 . It supplies the mark signal data as. This allows for recording, such as recording start point mark signal MK _{P1S, P2S} MK, MK _P3S as the recording end point mark signal MK _{P1E, P2E} MK, MK _P3E (claim 23 (c) Fig.).

In this embodiment, the mark signals MK _OS and MK _OE , MK _OE and MK _P1S , MK _P1S and MK _P2S , MK _P3E and MK _P3E, etc., respectively, are tape position address values relative to the reference point at the top of the tab of the video tape 36, respectively. It consists of. The tape position address value is diagrammatically achieved by transferring the count value of the tape counter circuit in the video tape recorder unit 3 to the control management data processing unit CPU 8 via the mechanism control unit CPU 11.

Therefore, the mark signals MK _P1S , MK _P1E , MK _P2S, and MK _P2E are index data indicating the start positions of the programs P1, P2, etc., that is, the positions corresponding to the number of system programs B4 recorded in the management database video track record field F _AVV . It is used as. When the mark signals MK _P1S , MK _P1E , MK _P1S and MK _P2E are respectively counted from the reference point at the top of the tap, the number of system programs such as programs P1 and P2 recorded for the same reference point is detected.

By the reproduction ranking data, the system program number (Fig. 6) for continuous reproduction is recorded from byte 1 to byte 32. When the user specifies and records the playback rank, the system program number of the program recorded in the current video cassette is recorded in the rank specified forward from byte 1 in the management data recording mode.

If the user does not enter any playback rank, the system program number of the program recorded in the current video cassette is recorded in the rank originally recorded forward from byte 1 in the management data recording mode.

It is desirable to record multiple programs in succession, and when the user specifies a rank in which the management data recording mode is selected for later playback of these programs, the number of system programs from byte 1 is recorded to the current video cassette in the designated rank. Replaced by that of the program to be If the user does not specify a play rank, the number of system programs that effectively follows the last play rank data before regeneration is recorded as play rank data for the newly recorded program. Therefore, when a plurality of programs are continuously recorded, the control management data processing unit CPU 8 inputs the management data recording mode to change the data of the repetitive recording count item A2, the regeneration item A6, and the like.

As described, it is possible to determine the reproduction rank by the predetermined reproduction rank data simultaneously with the recording of the program. For example, when a plurality of programs constituting a series of dramas are recorded in random order on one tape, a ranking for reproducing these programs later may be specified in advance.

Thus, the recorded program is easily reproduced in the predetermined rank using the mark signals MK _P1S , MK _P1E , MK _P2S and MK _P2E and the start address data item B1 for each program in addition to the reproduction rank data. This property boosts the level of convenience that video tape recorder 1 provides.

[(2) Program Play Mode]

As described with reference to FIG. 8, when the user selects the "autoplay" item in the management data list on the display screen in step SP21, the control management data processing unit CPU 8 enters the program play mode, In step SP31, the automatic playback process is performed.

That is, when the recorded video cassette 35 is loaded into the video tape recorder unit 3, the control management data processing unit CPU 8 enters the management database reproduction mode when communicating with the mechanism control unit CPU 11 Let's do it. In the management database reproduction mode, the control management data processing unit CPU 8 picks up the data video signal from the management database video track record field F _AVV of the video tape 36, records the signal in the register 44, and picks up the pickup. The signal is forwarded through the magnetic head 34, the video electromagnetic conversion circuit 33, the playback circuit 37, the playback switch over circuit 38, and the video recording decoder 52.

In this way, the register 44 holds the management data D _AV (FIG. 4) as data specified on the current video tape 36. As shown in FIG. Therefore, reproduction data and program data D _PRX (Fig. 6) for programs P1, P2, P3, and the like are retained.

In the above-described manner, the register 44 constitutes a centralized control device on the program position on the videotape, and the start address item B1 and the end address item B2 of the program data D _PRX including the position data are the programs P1, P2, P3 and the like. Recording start and recording end points of MK _P1S and MK _P1E , MK _P2S and MK _P2E , MK _P3S and MK _P3E , and the like, each point being the start of a predetermined program on the video tape 36 relative to the reference point at the top of the tape, or This is an address indicating the end position.

As described in FIG. 27, the CPU 8 in the program reproducing mode moves from step SP90 to step SP91. After detecting the number of system programs using the reproduction rank data in the register 44, the CPU 8 detects the start address of the specified system program number.

Simultaneously with the start of the program reproduction, the CPU 8 detects the number of system programs recorded in byte 1 of the reproduction priority data.

The CPU 8 then proceeds to step SP92 where the system program number is checked as if specified in the reproduction priority data.

Since the number of system programs is detected in byte 1 of reproduction priority data at the same time as the start of program reproduction, the CPU 8 proceeds to step SP93. In step SP93, the CPU 8 outputs the control data S6 to the mechanism control unit CPU 11 via the bus 10, so that the video tape recorder 1 is switched to the playback mode.

When the mark signal MK _P1S is detected, the CPU 8 follows the mark signal MK _P1S and checks as if the recorded program is a program indicated by the number of system programs recorded in byte 1. If the test result is positive, step SP94 is reached.

Thereafter, the CPU 8 remains in the playback mode until the next mark signal MK _P1S is detected. At this point, the CPU proceeds to step SP92.

When the program recorded on the top of the tape is designated to be reproduced first, the CPU 8 performs steps SP92, SP93, and SP94. These steps cause the video tape recorder 1 to play the program.

After detecting the number of system programs recorded in the reproduced priority data, the CPU 8 proceeds to step SP93 through step SP92.

The other program whose system program number of the program located on the tape top side is not recorded in byte 1 of the reproduction priority data, or where the program recorded on the tape top side is played first, and the system program number is specified in the follower data which is followed. Is designated to be reproduced, and the result of the inspection by the CPU 8 in step SP93 is negative. In this case, the CPU 8 proceeds to step SP95.

In step SP95, the CPU 8 checks as if the system program number of the next program to be reproduced is on the tape end side. If the result of the test is positive, the CPU 8 proceeds to step SP96. In step SP96, the CPU 8 fast forwards the video tape 36 until the mark signal MK _P2S is detected. The CPU 8 then proceeds to step SP97.

In step SP97, the CPU 8 checks as if the tape is finished. If the inspection result is negative, the CPU 8 proceeds to step SP93. In step SP93, the CPU 8 checks as if the current number is the number of system programs specified in the reproduction priority data.

As described, the program on the top of the tape is played first, and when another program reached by skipping the program immediately followed is played back, or the program on the top of the tape is played for the secondary program. In the case of being skipped, the CPU 8 repeatedly returns to SP93 through steps SP93, SP95, SP96, SP97. When the inspection of step SP93 finds out that the current number is the number of system programs specified in the reproduction ranking data, the programs are reproduced one after another within the predetermined ranking.

If the result of check in step SP95 is negative, the CPU 8 proceeds to step SP98. In step SP98, in contrast to what happens in step SP97, video tape 36 is rewound until mark MK _P2S is detected. The CPU 8 then checks in step SP99 as if the tape top is reached.

If the result of the check in step SP99 is negative, the CPU 8 proceeds to step SP93 and checks again as if the number is the number of system programs specified in the reproduction priority data.

If the checking in step SP93 indicates that the system program number of the already reproduced program is specified again for reproduction, the system proceeds to step SP94. In step SP94, the CPU 8 reproduces the program again.

When the system program number of the program recorded on the tape top side is specified by following the already reproduced program, the inspection result of step SP93 is negative. The CPU 8 then proceeds to step SP95.

As described, when the system program number of the program recorded on the top of the tape is designated by following the already reproduced program, the CPU repeatedly returns to SP93 through steps SP93, SP95, SP98, SP99. When the inspection result in step SP93 is fixed for the number of system programs specified in the reproduction ranking data, the video tape 36 is rewound for reproduction of each program at the previously designated ranking.

In this step repeated as necessary, one program can be repeatedly played back, or a plurality of programs recorded at random in the correct broadcast rank can be generated according to the rank designated in the play rank data.

If the system program number of any program is not recorded in the currently designated video cassette 35, the CPU 8 proceeds to SP100 only in accordance with the positive result achieved in step CPU97 or SP99.

In this regard, the CPU 8 displays an error message on the monitor 4 and the display screen 6A of the remote controller 6. The CPU 8 then proceeds to step SP101 and ends the processing.

At that time, the CPU 8 waits for input by the user from the remote controller 6 or the keyboard 12.

When all programs of the number of system programs specified in the reproduction ranking data have been reproduced, the inspection result of step SP92 causes the CPU 8 to proceed to step SP102.

In step SP102, the CPU 8 outputs the control data S6 to the mechanism control unit CPU 11 via the bus 10, rewinds or forwards the video tape 36 at a high speed to the program reproduction start position, and processing is performed. If it is finished, the process proceeds to step SP103.

The above-described setup records the play rank data of a program recorded in the video cassette on top of the tape. The video tape recorder according to the present invention is more convenient for the user because the program is reproduced without user intervention in a predetermined rank according to the play rank data.
